Norvasc (Amlodipine Besilate)

Amlodipine besilate, the active ingredient in Norvasc, is a calcium channel blocker presented as an oral tablet for oral use. It lowers elevated blood pressure and relieves chest pain caused by reduced blood flow to the heart, and is prescribed for adults with hypertension or chronic stable angina.

GNH USA supplies Norvasc as a licensed, GDP‑compliant international pharmaceutical supplier serving hospitals, pharmacies and clinics worldwide. The company adheres to EU quality standards and provides reliable sourcing for regulated markets globally.

Amlodipine besilate (Norvasc) is used to manage cardiovascular conditions that involve elevated vascular resistance.

Hypertension: reduces systolic and diastolic blood pressure to lower cardiovascular risk. Chronic stable angina: improves myocardial oxygen supply by dilating coronary arteries. Coronary artery disease: decreases cardiac workload and helps prevent angina episodes.

Amlodipine besilate may cause a range of adverse reactions.

Common Side Effects: - Peripheral edema: swelling of the ankles or feet. - Headache: mild to moderate intensity. - Flushing: warm sensation and reddening of the skin. - Dizziness: sensation of light‑headedness, especially on standing.

Serious or Rare Side Effects: - Severe hypotension: markedly low blood pressure requiring medical attention. - Myocardial infarction: rare occurrence of heart attack. - Hepatic dysfunction: abnormal liver enzyme elevations. - Allergic reactions: rash, pruritus, or anaphylaxis.

Before initiating therapy, certain precautions should be observed.

Monitor blood pressure: ensure adequate control and avoid excessive reduction. Assess liver function: adjust use in patients with hepatic impairment. Caution in heart failure: monitor for worsening symptoms. Avoid abrupt discontinuation: taper dose to prevent rebound hypertension. Use with caution in the elderly: start at lower doses due to increased sensitivity. Store at room temperature: keep in the original container, protect from moisture and direct sunlight.

Amlodipine besilate can interact with several medicines.

Major Interactions (Avoid): - Simvastatin: increased risk of statin‑related myopathy. - Strong CYP3A4 inhibitors (e.g., ketoconazole): may raise amlodipine plasma levels. - Grapefruit juice: can elevate drug concentration.

Moderate Interactions (Monitor Closely):\n- Beta‑blockers: may enhance antihypertensive effect. - Diuretics: combined use may cause excessive blood pressure reduction.
